guile-gnome removal

[Greg Troxel <gdt%lexort.com@localhost>]

guile-gnome 

  wraps gtk2 and gnome2, both obsolete
  is unmaintainted upstream (last release 2017)
  uses guile 2.0
  doesn't actually work
  is likely used by zero people

so I plan to delete it from pkgsrc no earlier than 1200Z on 10 November.
Please speak up if that's a problem.

I also intend to, when I get to it, add guile-gi and g-golf.   But I am
not seeing adding those, which should happen  anyway, and pruning
guile-gnome, as needing synchronization.

g-golf is the guile-world's current approach to wrapping gnome:

guile-gi is for gobject-introspection:
